When the process is
corrosive to gauges with bronze/brass wetted parts, an
alternative was to isolate the gauge from the process
with capillary and isolators or diaphragm seals. Now,
when the process is compatible with 316 stainless steel
or Monel, Ashcroft® Inc. offers the new Ashcroft®
Types 1127 or 1128 differential pressure gauges with
4.5" or 6" dial sizes.
